3003 Filter Module
Description 
The 3003 filter is a voltage controlled, discrete analog 18 db/oct ladder low-pass filter, employing hand-matched transistors. 
Drop the FREQUENCY knob to 0 and things get pretty dull; swing it back up and those "Transistor Bass” highs come crashing 
through the gate. The 3003’s RESONANCE circuit at max will sing out more than the TB’s signature chirping in a fun, bubbly, 
if  washy, poorer relation, Mini “clone-ish" way; use it tastefully, or throw moderation to the wind for overwhelming chirp force.  
!
Our 3003 filter has the most gentle sonic touch of  its partners in the Boomstar fold, but nevertheless is quite capable of  
shaping precise, very dynamic tone. Whether or not this STUDIO ELECTRONICS filter is filling its traditional baseline boxing 
niche, driving a harsh, liquid, acid-like tone, a softer more rubber-bandy SH-101-ish presence, or out of  the bass range 
altogether, leading the way, all is within easy reach of  this surprisingly warm and versatile VCF. The 3003 can be distinctly 
vocal at times, especially when one is willing to put grittier, more distorted desires aside.
